Product Description
Advanced Manufacturing for Demanding Industrial Applications
We specialize in high-precision OEM forging and CNC machining, delivering custom-engineered components that meet the most stringent performance requirements. Our closed-die forging, precision CNC machining, and finishing processes ensure superior strength, dimensional accuracy, and durability—ideal for critical applications in aerospace, automotive, oil & gas, heavy machinery, and defense.
Precision Forging Services
Closed-Die (Impression Die) Forging
Process: Heated billets are pressed into custom dies under extreme pressure, forming near-net shapes with excellent grain flow.
Benefits:
- Higher strength-to-weight ratio vs. casting or machining
- Improved fatigue & impact resistance due to optimized grain structure
- Reduced material waste compared to traditional machining
Materials: Carbon steel, alloy steel, stainless steel, titanium, aluminum, brass
Open-Die Forging
Process: Used for large, simple shapes (shafts, rings, blocks) where dimensional tolerances allow secondary CNC machining.
Applications: Heavy industrial components like rolls, cylinders, and large flanges
Cold & Warm Forging
Cold Forging: Room-temperature forming for high-strength, tight-tolerance parts (fasteners, gears)
Warm Forging: Reduced heating for better formability than cold forging, with improved mechanical properties
High-Precision CNC Machining
After forging, parts undergo CNC turning, milling, grinding, and EDM to achieve ultra-tight tolerances (±0.001" or better).
Key CNC Machining Capabilities
5-Axis CNC Milling - Complex geometries with high accuracy
CNC Turning - Precision shafts, bushings, and threaded components
Grinding (Surface/Cylindrical) - Ultra-fine finishes (Ra 0.2µm or better)
Gear Hobbing & Shaping - High-accuracy gear manufacturing
EDM (Wire & Sinker) - Intricate contours and hardened materials
High-Tolerance Precision Forging Capabilities
